Product Description
Technical data
Optimized medium pressure pump for high CZPT machines.
Sizes 45 to 180.
Nominal pressure 280 bar.
Maximum pressure 350 bar.
Open circuit.
Features
Variable displacement pump with axial piston rotary group of swashplate design for hydrostatic drives in open circuit.
Flow is proportional to the drive speed and displacement.
Flow can be infinitely varied by controlling the swashplate angle.
Hydrostatically unloaded cradle bearing.
Port for measurement sensor on high pressure port for all sizes with port plate 22 and 32.
Low noise level.
Increased functional reliability.
High efficiency.
Good CZPT to weight ratio.
Universal through drive for all sizes with port plate 22 and 32.
Optional pulsation damping.
